What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer In rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit descriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both firmware-controlled). The result can exceed RTK_PCI_RX_BUF_SIZE (11478), causing an out-of-bounds read from the pre-allocated DMA buffer when skb_put_data copies new_len bytes. The USB transport already validates this (rtw_usb_rx_data_put checks against RTW_USB_MAX_RECVBUF_SZ); the PCIe path does not. Add a check that new_len does not exceed the DMA buffer size.

Source: EUVD (ENISA), in the words of the advisory.
